Soil structure and earthworm activity under different tillage systems in organic farming [PDF]

open access: yes, 2007
Organic farmers are encouraged to adopt conservation tillage to preserve soil quality and fertility and prevent erosion. However, many studies in different soil and climate conditions have demonstrated that the compaction of the untilled layer is higher ...

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

open access: yesAdvanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Mapping soil degradation using remote sensing data and ancillary data: South-East Moravia, Czech Republic

open access: yesEuropean Journal of Remote Sensing, 2019
Data on the real extent of soil that is degraded by erosion represent important information for the purposes of conservation policy. However, this type of data is rarely available for large areas.

Integration of Spatiotemporal Multi‐Omics in Peach Fruit Unravels a Metabolic Niche and the Genetic Basis of Trichome‐Mediated Stress Adaptation

open access: yesAdvanced Science, EarlyView.
This study constructed the first spatiotemporal multi‐omics map of peach fruit and discovered a key candidate gene that synergistically regulates trichome development and drought tolerance through the jasmonic acid signaling pathway, providing insights into the coupling mechanism between development and stress resistance.

Plant Genetic Engineering: Technological Pathways, Application Scenarios, and Future Directions

open access: yesAdvanced Science, EarlyView.
This review maps the fast‐evolving landscape of plant genetic engineering, linking enabling platforms with trait‐focused applications in architecture optimization, stress resilience, yield improvement, and quality enhancement. It highlights how genome editing, transgenic strategies, and emerging multi‐gene approaches reshape breeding pipelines, while ...

Mitigation of Greenhouse Gas Emissions Through Straw Management and Oxygenated and Biochar-Based Fertilizers

open access: yesPlants
Straw returning is a common agricultural practice that can enhance rice (Oryza sativa L.) yield in paddy systems. However, it also leads to a significant increase in greenhouse gas emissions (GHG).

Heavy metals phytoextraction from heavily and moderately contaminated soil by field crops grown in monoculture and crop rotation

open access: yesSoil and Water Research, 2011
The uptake of Pb, Cd, Zn and biomass production of the plants Brassica juncea v. Opaleska, Triticale hexaploides var. Gabo and Helianthus annuus v. Maritza were observed in a field (trial) and a pot experiments during four years. The plants were grown in

Estimating Percent Residue Cover Using the Line-Transect Method [PDF]

open access: yes, 2009
Leaving crop residue on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop
